IMPROVEMENT IN SIFTING-SHOVELS.

Specification forming part Qf Letters Patent N0. 127,405, dated June 4, 1872.

aet description thereof, reference being had to the aceompanying drawing and t-0'the letters of reference marked thereon making a part of this speoifieation.

Myinvention relates to improvements in siftingshovels, a.nd more particularl y to improvements 011a siftin g-shovel on which a patent was granted to Paul A. Sabbaton 0n the 4th day of J anuary, 1859, and numbered 22,514. The 0bject o f my improvements is to make the shovel much more durable and last-ing, by introducin g, i n a peculiar and novel manner, better and m0re durable materialat the edge 01 front end 0f the shovel, such as east-steel, or what has proved best is what is known as English blister-steel. These shovels being mostly used about gas-works for handling and removing coke, in a few days wear the edges so a-s t0 render them useless unless protected by some suitable material; These shovels hzwe heretofore been made 0f soft malleable iron, which has proved entirely unfit for the edges of the shovels. The nature of my invention consists in forming a piece of steel suitable for the edge of the shovel, in which is provided several holes near the back edge, or at any proper 1 point, and when so prepared it is molded. in

the sand with the shovel-pattern in such a way that the molten metal Will fill all the holes. At the same time the iron covers that portion 0f the steel where the holes are 1nade, so that the steel is thns secured t0 the shovel in the most rigid am! substautial manner. The steel may also be secured in a very rigid way t0 the shovel by casting lugs 01' rivets ab the poinl; where the shovel joins t-l1e steol, so as t0 fit;

corresponding holes made in the steel and riv-- eted together, and in this way making a. very convenient and durable shovel.

T0 enable others skilled in the anrt to make and use my invention, I will proceed 130 describe its construction.

Figure I represents my improved shovel. Fig. II represents the steel edge, provided with holes, ready 120 be molded in the sand 01 riveted t0 the shovel.

Letters of like name am]. kind refer to Iike parts in each 0f the figures.

A represents the shovel containinig my improvements, the genera-l form of which I do not claim as' any part of my invention. B represents a steel 'edge, provided. with holes a a, which is made thin and of suitable shape to form 01 constitute the edge of the sh.ovel. This steel edge B is molded. in the sandl in such a manner tht the molten metal is run into the holes and upon the steel, thus riveting the steel firmly within the iron 01' lugs 01 rivets may be cast upon that portion 0f the shovel where it joins the steel to fit corresponding holes a a, and the sceel placed thereon and riveted firmly thereto, whieh forms a steel edge to the. shovel, which edge may be brought to any degree 0f hardness desired, thus making a mueh more desirable and 1asting cast shove] than has hitherto been used..

'Having thus described my invention, what I claim, and desire to secure by Letters Patent of tl1e United Staates, is-- As an article of manufaeture, a east malleab1e sifti11g-shovel, having a steel edge united by flowing the cast; metal a-Toun it, as described.
